Some Problems about BrokenProcessPool in SpikeTutorials 0.99 #2310

Closed holawa closed 7 months ago

holawa commented 9 months ago

Dear developers ! I am using 0.99.1 SpikeInterface on windows10, my computer has 64GB RAM, and I meet some problems when I try to learn something from the tutorial. BrokenProcessPool seems to occur everywhere. Indeed I doubt it occurs when I try to use the Variable job_kwargs,wether in .save() , spykingcircus2 or tridesclous2 Actually, serveral weeks ago, I didn't meet BrokenProcessPool when I followed the tutorial. And I'm really need your help.

①In the [Official_Tutorial_SI_0.99_Nov23] Capter 3 Saving and loading SpikeInterface objects


if (base_folder / "preprocessed_compressed.zarr").is_dir():
    recording_saved = si.read_zarr(base_folder / "preprocessed_compressed.zarr")
else:
    import numcodecs
    compressor = numcodecs.Blosc(cname="zstd", clevel=9, shuffle=numcodecs.Blosc.BITSHUFFLE)
    recording_saved = recording_sub.save(format="zarr", folder=base_folder / "preprocessed_compressed.zarr",
                                         compressor=compressor,
                                         **job_kwargs)

When I run the code block above, it returns BrokenProcessPool information

If I run the sorters in Docker, such as kilosort2, mountainsort4, tridecircus, ironclust, etc. They're all good, except when I run a huge(maybe) data in spykingsort image(the tutorial data is OK with no error), I meet the same problem with #895.However,I feel sorry that I am just a new learner , I can't manage to solve the problem by setting the parameters (just because I don't know where to set , use whith function to set).

Hi @holawa

1. for this kind of bug that occur in multiprocessing (n_jobs>1)

BrokenProcessPool: A process in the process pool was terminated abruptly while the future was running or pending.

The easiest is to use n_jobs=1 and get a better trace for the bug.

  1. We did a recent fix spkykingcircus in code if you install spikeinterface from source maybe this could fix it.

  2. Same as 1

In short could try to run the same notebook with n_jobs=1 ? And repost error here ?

Thank you again!

Hi @holawa

for this kind of bug that occur in multiprocessing (n_jobs>1)

BrokenProcessPool: A process in the process pool was terminated abruptly while the future was running or pending.

The easiest is to use n_jobs=1 and get a better trace for the bug.

  1. We did a recent fix spkykingcircus in code if you install spikeinterface from source maybe this could fix it.
  2. Same as 1

In short could try to run the same notebook with n_jobs=1 ? And repost error here ?

samuelgarcia commented 9 months ago

For 1, this is a good news but this must be very slow. Maybe you could try a few n_jobs. How many core do you have on your machine ? For the bug 2 and 3 I think, this is also because inetrnally tdc2 orsc2 are doing multiporcessing and sometimes is going wrong in your case.

holawa commented 9 months ago

Thank you ! @samuelgarcia

For ①, sadly, if I set other n_jobs, it may get wrong. when I set the n_jobs as 2 , I can get the message

write_zarr_recording with n_jobs = 2 and chunk_size = 30000
write_zarr_recording: 0%
0/300 [00:01<?, ?it/s]
---------------------------------------------------------------------------
BrokenProcessPool                         Traceback (most recent call last)

Almost the same as before.

For ② and ③ I have no idea, sorry. Multiporcessing seemed run well in this computer several weeks ago, and I used to run the Tutorial 0.99 with no modification. Is there a good way to solve the problem about multiporcessing ? My computer in lab uses Intel i9-10900 and has 10 cores with a 64GB RAM. If I run n_cpus = os.cpu_count() I can get the number 20. Actually this computer has two users, another user(administrator) went another lab, and I set my count(no administrator) on this computer. I set the remote connection on win10 so I can use it wherever I am. Everything went well until this week, I tried to test a new sorter "Klustra" in docker, then I found I got a message as no module named 'Spikeinterface'. I was shocked and ran pip install spikeinterface[full,widgets] pip install --upgrade spikeinterface[full,widgets]several times and reboot the computer. Then I found I can't run well with SpikeTutorials 0.99, ①②③ occured and I got terrible.

zm711 commented 9 months ago

I haven't directly tried the dataset from the tutorial, but using some simulated data, and mimicking the tutorial, I am able to get multiprocessing to work. I think @h-mayorquin's comment, may be pertinent to this in that on Windows there is an inconsistent need to use name==main in Windows specifically in the Spikeinterface context. I never need to use (thus far), but I also don't try to run full scripts (I typically do a more cell by cell approach).

Other possibilities I can think of is that my computer isn't hyperthreaded so it has 8 physical and 8 logical cores. I'm not sure if the multiprocessing for Windows struggles with logical cores or not. I have administrator privileges, but I don't typically run my python as admin, so I don't think that should be the problem.

@holawa,

One question I have is how are you running the tutorial. In a juypter notebook or did you try to copy the cells into a standard .py file? I'm not sure how if __name__ == '__main__' could fit into a juypter context, but maybe @samuelgarcia could answer that better.

holawa commented 9 months ago

Thank you! @zm711 Your words touched me ! I run the tutorial in jupyter lab since I knew Spikeinterface. I usually run these blocks step by step, but I never run them in .py files. I think I could try this way, for my computer is running a 54GB data in Spikeinterface , mountainsort4 , I will test this idea immediately when the task is over.

I think it's a nice way for .py file running in windows and I wrote a short .py file to try SpykingCircus2 in Spikeinterface. For convenience I have make a preprocessed file, so I could load the variable recording_saved.

import spikeinterface
import spikeinterface.full as si
import spikeinterface.extractors as se
import spikeinterface.widgets as sw
import probeinterface as pi
import os
from probeinterface.plotting import plot_probe,plot_probe_group
from pathlib import Path
import warnings
warnings.simplefilter("ignore")

if __name__ == '__main__':
    base_folder = Path('C:/Users/Melody/Desktop/test0')
    n_jobs = 1
    job_kwargs = dict(n_jobs=n_jobs, chunk_duration="1s", progress_bar=True)
    if (base_folder / "preprocessed").is_dir():
        recording_saved = si.load_extractor(base_folder / "preprocessed")
    else:
        recording_saved = recording_sub.save(folder=base_folder / "preprocessed")
    print(recording_saved)

    #In Spikeinterface spykingcircus2
    sorting_SC2 = si.run_sorter('spykingcircus2', recording_saved, 
                            output_folder=base_folder / 'results_SC2',
                            verbose=True,
                            job_kwargs=job_kwargs
                            )

It could work, however, it returned

I haven't directly tried the dataset from the tutorial, but using some simulated data, and mimicking the tutorial, I am able to get multiprocessing to work. I think @h-mayorquin's comment, may be pertinent to this in that on Windows there is an inconsistent need to use name==main in Windows specifically in the Spikeinterface context. I never need to use (thus far), but I also don't try to run full scripts (I typically do a more cell by cell approach).

Other possibilities I can think of is that my computer isn't hyperthreaded so it has 8 physical and 8 logical cores. I'm not sure if the multiprocessing for Windows struggles with logical cores or not. I have administrator privileges, but I don't typically run my python as admin, so I don't think that should be the problem.

@holawa,

One question I have is how are you running the tutorial. In a juypter notebook or did you try to copy the cells into a standard .py file? I'm not sure how if __name__ == '__main__' could fit into a juypter context, but maybe @samuelgarcia could answer that better.

zm711 commented 9 months ago

Sorry I mean try number 1 with the the script. So something like:

job_kwargs = dict(n_jobs=4, chunk_duration='1s', progress_bar=True)
if __name__ == '__main__':
     recording_saved = recording_sub.save(format="zarr", folder=base_folder / "preprocessed_compressed.zarr",
                                         compressor=compressor,
                                         **job_kwargs)

I wanted to test multiprocessing first. It seems like there is a separate multiprocessing-thread based issue that we also need to think about. But I want to see if we protect your recording.save() if that will work with n_jobs >1. Could you start with that and then we can try a sorter after that.

zm711 commented 9 months ago

Could you also let us know the version of threadpoolctl you have? You can just type conda list in the environment containing spikeinterface. (Although it appears you are working in base instead of a conda env is that true?)

holawa commented 9 months ago

I feel sorry that I failed. I wrote a code block like this, and replaced the old one

PS C:\Users\Melody\Desktop\test0>
Anyway, thank you! @zm711
zm711 commented 9 months ago

No worries. There is a known bug in threadpoolctl 2.x, so it might be worth while to update threadpoolctl to 3+ and see if that fixes it. The threadpoolctl 2.x can lead to the None not having attribute split. Could you try to update and then repeat the sorting and see if that helps?

holawa commented 9 months ago

Really, really, really thank you! @zm711 I update the threadpoolctl 2.2to threadpoolctl 3.2 and ① ② ③ went all well. Even if I set the n_jobs to other numbers, the code went stable and I feel much better !

Thanks @zm711. Maybe we should bump up the minimal version of threadpoolctl. I will take a look at that and then close this.

zm711 commented 9 months ago

Maybe with the switch in #2218 it led to this issue with threadpoolctl coming up. It happened two weeks ago so the timeline makes sense. But yeah based on my reading I think it is probably better just to have a minimal version (but if you discover something else with your reading do let me know!)

alejoe91 commented 9 months ago

Not sure it's related to #2218 since that only affected the PCA computation and quality metrics

zm711 commented 9 months ago

You’re right. I think it was just an old install. I support @h-mayorquin ‘s idea to just put in a minimum version so that if someone has an old install we make sure SI doesn’t have a buggy threadpoolctl.

vncntprvst commented 7 months ago

Just a note that this error can occur, even with threadpoolctl >= 3.2.0, when not enough memory is available (with respect to chunk size). This is something that happens to me sometimes when debugging code on a remote cluster node, and I did not request as much memory as when running jobs. The issue would not easily be fixed by job_kwargs optimization, because the total memory and number of cores on the node is not the same as the number reserved for the job.

zm711 commented 7 months ago

@vncntprvst Thanks for this. If we get enough votes @samuelgarcia might become magically inspired to work on this :).

I think you raise a good point though. I think there are two separate problems:

1) have threadpoolctl < 3 leads to the actual issue here. the None attribute error would be fixed by fixing threadpoolctl. 2) if the job_kwargs are not tuned properly then the parallelization will break (as you see) and currently the job_kwargs require the user to tune rather than having spikeinterface aid the user in tuning them to appropriate conditions.

I think we need to both bump the threadpoolctl, but also have a job_kwargs_optimizer (but that's my opinion of course).

Thanks again.
